Tyranny is tyranny, whether it's from government or from the corporate world and belongs on the end along with your statism or totalitarianism. After al, aren't you just handing control over to another entity in both? And that entity is still taking away your freedoms, whether it is control over you directly, or control over your life through your work life. If to the extreme right you have anarchy, how in the world can there by corporate tyranny since anarchy is by definition the lack of government, ie and overseer of any kind. I'm with you in that also to that extreme, something or someone will greedily take over, probably by force. But you can also argue that in the other extreme, pure utopia will never happen either, because some will refuse to labor for the good of the many...
So I am still going to argue to the left is control, to the right is liberty. Each extreme is wrong, be it total communal control, or total anarchy.
